Doped organic semiconductors explored

Organic semiconductors are already being employed in solar cells and organic LEDs (OLEDs). Until now, however, little was known about how the doping molecules are integrated into their chemical structure. Scientists have now analyzed this question at BESSY II with surprising results. The molecules are not necessarily uniformly dispersed in the host lattice, but instead form co-crystallites. It is this very species that takes over the role as the actually doping molecule.
